Etymology

The word 'irrational' originated from the Latin word 'irrationalis', which means 'not endowed with reason'. Its usage in English dates back to the early 15th century. Initially, the term was predominantly associated with philosophical discussions on human behavior and thought processes. Over time, the word evolved to encompass various contexts, including mathematics, where it refers to numbers that cannot be expressed as fractions. Today, 'irrational' is commonly used to describe behavior or beliefs that lack logical reasoning.
